Zooanthid?

[jhornik]

I don't know what's up in my tank and I've never had this problem before, but I can not seem to keep zooanthids alive in my bio-cube! Water parameters are all good, calcium good, and I have 4 36W power compact lights over a 29 gallon bio-cube. I have plenty of other corals that are thriving too. I have 3 diff acans, a frogspawn, xenia, ricordia, a bulb tip, and even some nuclear green paly's that are thriving. Any suggestions, ideas, or hypotheses on what could be up?

Thanks,

Josh

What is happening to them? Are they just disappearing, melting away, getting fungus, etc.?

sounds list it could be a pest.

Could be a group of nudis or spiders. Good luck and let us know.

I've checked and dipped for pest and have found nothing. A while ago it looked like amphipods were eating them but I came to the conclusion they were probably just eating what was already dead because I could not find anything about zoo eating amphipods or copepods. I've searched several times now for spiders, nudi's and snails and have found nothing. Other than that at times it'll look like the tentacles have been eaten off or the whole zooanthid polyp just looks withered almost. I think it seems strange I'm having no problems with the play's as they have the same predators and diseases right?

Maybe try a freshwater dip, some of these pest can be very hard to bring out. If you have some lugols maybe try that too. What dip method did you try?

I've tried the fresh water dip so far.
